An Iranian naval base in Konarak, located in the country's southeast, was struck by fighter jets on Thursday evening.
The attack, which occurred in two stages and resulted in two explosions, was confirmed by Mohammad Younes Haqqani, the governor of Konarak County, according to reports from the IRNA news agency.
The incident marks a further escalation in the ongoing military confrontation between Iran and the United States.
Iranian armed forces have previously launched attacks on US military infrastructure in neighboring Gulf states, while Iranian authorities have accused the US of striking the perimeter of the Bushehr nuclear power plant.
This latest strike on a domestic naval facility suggests the conflict is expanding beyond cross-border exchanges.
For markets, the development reinforces the geopolitical risk premium embedded in energy and shipping prices.
